4. Insect Bites
Bites from any crawling or flying insect can result in health problems as mild as skin irritation to more severe and life-threatening issues. The reason why insect bites are amongst the list of unusual causes of swollen ankles is that feet are easily exposed to insect habitats. For example, wearing sandals or shorts exposes your ankles, feet, and legs. If you come in contact with insects, these uncovered body parts would be at risk of being bitten.
Depending on the reaction of your body and the type of insect, the stings and bites are benign, mild, and severe. People allergic to insect stings, for example, bee stings can react badly and swell the whole body. The most common insects that have a record of attacking humans are bees, spiders, wasps, and mosquitoes. Some of these insects are disease transmitters, it is recommended that you seek medical attention if bitten.
